蒸汽压缩式空气源热泵系统因其结构简单、投资少而得到广泛应用。然而，在寒冷地区，该系统用于空间或水加热时存在一系列问题，并且在过去的二十年中，许多研究小组做了大量工作来改进VCASHP系统以解决这些问题。本文综述了近年来在寒冷地区应用VCASHP系统的最新进展。本文将先进的系统分为三大类：单级、双级和多级压缩系统。此外，双级压缩系统根据压缩机和独立回路的数量分为准两级、两级和级联压缩系统。分析和总结了不同工质和中间结构的各类压缩系统的制热性能和特点。同时，提出了这些先进系统在寒冷地区推广应用中存在的问题。希望本文的研究内容和提出的问题能对从事这一领域的研究人员有所帮助。
Vapor compression air source heat pump (VCASHP) system has been widely applied due to its simple structure and low initial cost. However, there are a series of problems when the system is operated for space or water heating in cold regions, and a number of research groups have done much work to improve VCASHP systems for solving these problems over the last two decades. This review presents an update on the recent advances in VCASHP systems applied in cold regions. In this paper, the advanced systems are classified into three major types: single-stage, dual-stage and multi-stage compression systems. In addition, the dual-stage compression system is divided according to the number of compressors and separate loops into quasi-two-stage, two-stage and cascade compression systems. The heating performances and characteristics of each type of compression systems with different working fluids and intermediate configurations have been analyzed and summarized. Meanwhile, several issues of these advanced systems that impede their widespread applications in cold regions are proposed. It is hoped that both the reviewed contents and proposed issues may be useful to the research fellows working in this field.
